I picked this up from another thread.
Right now the civilians run around rather aimlessly and thus get shot down.
Dont get me wrong, I like that civilians notice aliens and then I could act
on this info and shoot the alien down.

But from a civilian that is afraid of aliens, he should either run away as much as possible,
or if that is not possible, try to find a "safe spot" where he could stay.
That actually brings me to another thing ... i think the maps could be
either a bit bigger, or there could be more stuff to hide behind ...
cupboards... furniture... walls which dont lead to a door...
or doors which can be closed or locked behind you...
